dualemac: fix to drop PTP sync msgs from unknown master
Re-adding this change as it was reverted in another commit.
In PTP implementation, firmware should drop sync messages that are not
from the PTP master (where master MAC addr is stored in SRAM by driver).
In DualEMAC build, the host_rcv flag is checked in different places than
Switch build, and to enable dropping unknown sync msgs needs to be
checked immediately after completing PTP timestamping function to
prevent the frame from being forwarded to host.
This change adds a check of host_rcv flag immediately after PTP
timestamping
function, to skip host rcv if set.
